What Material Are Thermocouple Made Of?

There are many types of thermocouples, and different thermocouple materials are also different. Let us briefly introduce the commonly used thermocouple materials.

1. Commonly used thermocouple materials are:

1, S type thermocouple; platinum rhodium 10-platinum thermocouple

2, R-type thermocouple; platinum rhodium 13-platinum thermocouple

3, B type thermocouple; platinum rhodium 30-platinum rhodium 6 thermocouple

4, K-type thermocouple; nickel-chromium-nickel-silicon thermocouple

5, N-type thermocouple; Ni-Cr-Si-Ni-Si thermocouple

6, E-type thermocouple; nickel-chromium-copper-nickel thermocouple

7, J type thermocouple; iron-copper-nickel thermocouple

8, T-type thermocouple; copper-copper-nickel thermocouple

2. The most commonly used in industrial production are K-type thermocouples and S-type thermocouples

K-type thermocouple is used as a temperature sensor and is usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure the surface temperature of liquid vapor and gaseous media and solids in the range of 0℃ to 1300℃ in various production.

S-type thermocouple, R-type thermocouple, and B-type thermocouple are collectively referred to as platinum-rhodium thermocouples

The platinum-rhodium thermocouple has a high temperature measurement range and has been used in high-temperature places for a long time. The measurable temperature of type B is as high as 0-1800℃
